3 Claims.

chair and the chair in the row forwardly there-- of, permitting readypassage of persons before the seated occupant of such a chair; toprovide such a chair whose seat may be upwardly tilted when notoccupied; to provide such a chair whose supporting standards may beadjustably angularly spaced to provide for row curvature of a pluralityof seats; to provide such a chair which is a modification of and animproved construction over the chair of my issued patent aboveidentified; and, to provide such a chair which is attractive inappearance, comfortable in use and reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanyingdrawings, wherein:

Figure 1 is a side elevational view of the chair whose relativelymovable seat and back are shown as in their normally occupied positions;

Figure 2 is a View similar to that of Figure l but showing therelatively movable seat and back moved by the occupant to a positionwherein others may conveniently pass before the occupant of such achair;

Figure 3 is a View similar to that of Figures 1 and 2 but showing theseat in its upwardly tilted position when unoccupied;

Figure 4 is an enlarged sectional View on line 44 of Figure 1;

Figure 5 is an enlarged sectional View on line 5-5 of Figure 1;

Figure 6 is an enlarged sectional view on line B6 of Figure 1;

Figure 7 is a sectional view on line '|--l of Figure 6; and

Figure 8 is a sectional view on line 88 of Figure '7.

Referring then to the drawings wherein like parts of the structure shownare designated by the same numerals in the several views, a pair ofspaced vertically disposed supporting standards Il! may be secured tothe floor as by bolts, not shown, and the opposite sides of eachsupporting standard I0 is provided with a boss ll whose outer surfacehas a semi-spherical well i 2.

Seat supporting plates is, here shown as triangular in form and havingan arcuate upper edge are each provided with a ball M at their base, onehalf of which ball is disposed in a well l2 of a boss I l of asupporting standard Ill and the other half of which is disposed in asemispherical well 15 of a clamp lfi'secured to a boss H by the bolt It,as best shown in Figures 4 and 5.

A seat supporting shaft I? is provided at each of its opposite ends witha bushing I 8 secured thereto by a rivet I 9 which bushings are eachseated and secured within an aligned opening of a plate 26 disposedtransversely of the shaft ll. An inverted U-shaped plate or saddle 2isheaths and embraces the opposite sides of each plate 20 to which it issecured as by rivets 22, each bushing H? on the shaft I? being projectedthrough an opening on the inner side surface of a saddle 2!, all as bestshown in Figures 7 and 8.

Each plate 26 has a rearwardly depending por tion 23 forwardly of whichthe upper portion of a triangular seat supporting plate I3 is positionedbetween the opposite sides of a saddle 2 I, the bottom linear edge ofeach plate 26 riding on the arcuate upper edge of each triangular plate53. As best shown in Figures '7 and 8, each triangular plate is providedwith a V-shaped slot 24 through which a pin 25 projects and which pin isriveted to the opposite sides of the saddle 2| to limit the forward andrearward movement of the triangular seat supporting plate.

A seat supporting pan 26 supporting the seat cushion 2'! is pivotallysupported on the shaft ll whose opposite ends project through bearingopenings in the opposite side flanges of the pan 26 as best shown inFigures 6 and 8 and the back 28 which ispivotally supported at itsopposite sides between the upper rear end of each supporting standardIII as by pivot pins 29 is likewise pivotally connected at its oppositesides adjacent its base to the opposite side flanges of the seatsupporting pan 26 adjacent the rear edge thereof by pivot pins 30'.

Since the seat supporting pan 26 is pivotally connected to the pivotallysupported back 28, the occupant of the chair may effect a movement ofthe seat and back from its normally occupied position shown in Figure 1to its position shown in Figure 2 in instances wherein the occupant ofthe chair desires to make more room for a person passing before him whenhe is occupying the seat, the pin 25 within each V-shaped slot 24 ofeach triangular seat supporting plate [3 limiting the forward andrearward movement of the relatively movable seat and back.

Since the seat supporting pan 26 is likewise pivotally supported on theshaft I1, the seat may be tilted upwardly to its position shown inFigure 3 when not occupied, the lowered or occupied position of the seatbeing fixed by the members 3|, each projecting from an opposite sideflange of the pan 26 and each of which engages the under surface of astop 32 projecting inwardly from the inner surface of a saddle 21 asbest shown in Figure 6.

Because each supporting standard [0 is provided with a ball and socketconnection with its triangular seat supporting plate I3, a row of chairsmay be disposed in arcuate fashion as is conventional in theatres andthe like and as is indicated by the dotted line disclosure in Figure 4.

It will thus be seen that the chair herein shown and described isattractive in appearance, comfortable in use and is reasonablyeconomical in manufacture and while but one specific embodiment of theinvention has been herein shown and described, it will be understoodthat certain details of the construction shown may be altered or omittedwithout departing from the spirit of the invention as the same isdefined by the following claims.

I claim:

1. A chair comprising a pair of spaced vertically disposed supportingstandards, a triangular seat supporting plate swingably connected at itslower corner with the inner surface of each standard, said triangularplates each having an upper arcuate edge between their upper corners, aplate disposed above each triangular plate in plane alignment therewithhaving a linear bottom edge in engagement with the arcuate upper edge ofits triangular plate on which it is adapted to rock, a shaft disposedand secured between the upper plates, a saddle embracing each upperplate to which it is secured and overhanging the opposite upper sideportions of a triangular plate, said triangular plates each having aV-shaped notch through which a pin projects and which pin is securedbetween the opposite side walls of the saddle for limiting said rockingmovement, a seat pivotally supported on said shaft, and a back pivotallysupported between said standards and pivotally connected to the rearsides of the seat.

2. A chair comprising a pair of spaced vertically disposed supportingstandards each having a semi-spherical well within its inner sidesurface, a pair of triangular seat supporting plates each having a ballat its lower corner seated within a well of a standard and each platehaving an arcuate upper edge between its two upper corners, a clampsecuring each plate to its adjacent standard having a semi-sphericalwell within which said ball is seated, a plate disposed above eachtriangular plate in plane alignment therewith having a linear bottomedge in engagement with the arcuate upper edge of its triangular plateon which it is adapted to rock, a shaft disposed and secured between theupper plates, a saddle embracing each upper plate to which it is securedand overhanging the opposite upper side portions of a triangular plate,said triangular plates each having a V-shaped notch through which a pinprojects and which pin is secured between the opposite side walls of thesaddle for limiting said rocking movement, a seat pivotally supported onsaid shaft, and a back pivotally supported between said standards andpivotally connected to the rear sides of the seat.

3. A chair comprising a pair of spaced vertically disposed supportingstandards, a seat supporting plate swingably connected adjacent itslower end with the inner surface of each standard, said plates eachhaving an arcuate upper edge, a plate disposed above each seatsupporting plate in plane alignment therewith having a linear bottomedge in engagement with the arcuate upper edge of its seat supportingplate on which it is adapted to rock, a shaft disposed and securedbetween the upper plates, a saddle embracing each upper plate to whichit is secured and overhanging the opposite upper side portions of a seatsupporting plate, said seat supporting plates each having a V-shapednotch through which a pin projects and which pin is secured between theopposite side walls of the saddle for limiting said rocking movement, aseat pivotally supported on said shaft, and a back pivotally supportedbetween said standards and pivotally connected to the rear sides of theseat.
